Abstract
An applicator for one of direct and indirect application of a coating medium onto a traveling fiber material web includes at least one dosing device and a coating edge delimiting device. The at least one dosing device includes a pair of lips with each lip having a free end adjacent the fiber material web and extending transverse to a direction of travel of the fiber material web. Further, the lips define a dosing slot therebetween. The dosing slot is an open-jet nozzle and has two side edges. The coating edge delimiting device includes at least two coating edge delimiting elements fitted between and in direct contact with each of the lips. The coating edge delimiting elements close off and substantially seal the dosing slot on the side edges, thereby substantially sealing the dosing slot. Each coating edge delimiting element has a wall section extending beyond the free ends of the lips in a flow direction of the coating medium through the dosing slot.
